MACHINE F OR PLANING AND PRINTING WOOD.

SPECIFICATION forming part of Letters Patent No. 291,155, dated January1, 1884.

Application filed December 15. 1882. (No model.) 7

To all whom it may concern:

Be it known that I,W1LLIAM A. COMPTON,

-a citizen of the United States, residing in the vices and thencedirectly to and through the The. printing devices are representedprinting devices, so as to plane and print the boards in one continuousoperation, and thus save the handling that is involved in printing uponthe planed surface of the wood in a machinesubsequent to the planing andcutting up .of the stuff.

The invention also consists in the appliances for carrying my improvedprocess into effect, and the latter are illustrated in the annexeddrawings, in which-- Figure 1 is a longitudinal central section of aplaning-machine provided with myimprovements. Fig. 2 is a plan of aboard having successive sections imprinted with a recurrent design. Fig.3 is an end elevation of the devicesfor printing enlarged, and Fig.- 4is a transverse section of the same on line 00 w in Fig. 6. .Fig. 5 is aside view of the wiper fitted to the front edge of the screen. Fig. 6 isa plan of the top of the bed, showing the driving? gearing for theauxiliary feeding -roll; Fig. 7, an alternative construction.

A is the frame of an ordinary planing-machine, the driving mechanismbeingentirely omitted, except the main counter-shaft B at one end of theframe, and only the receiving feedrollers O, the cutter-heads D, and thedelivery feed-rollers 0 being exhibited.

as mounted upon stanchions I), set upon the frame A beyond the rollersC, so that the latter may propel the boards E into the printing devices.The latter are adapted to impress a uniform coat of .color upon themoving board, or to print anydesi-red design by means of astereotype-roller ora gum impression transfer-roller. The color or inkwould in either case be carried in a trough and transferred to theimpression-roller by a distributing-roller, as in other ink-printingmechanisms. A suitable arrangement is shown in Fig. 4, in which a is theink-trough, c is the ink-roller, d is the distributing-roller, and c isthe impressionroller, of whatever kind may be preferred.

The roller 6 is mounted upon a shaft, 6, in boxes 6, verticallyadjustable in the stanohions b, and screws Z) are fitted to the boxes 0,to adjust them above the table A of the plan ing-machine the requireddistance. To secure an elastic pressure of the roller 6 upon the boardas it passes beneath the roller, the screws 7) are provided withindia-rubber washers a, adjusted between the collars of the screws andtheir bearings in the tops of the stanchions Z).

The screws are provided with square heads at the top to fit a suitablekey or wrench, and may thereby be adjusted independently to secure aperfect impression, although both screws may be connected by across-shaft and gearwheels, if preferred, so as to be moved simul=taneously.

In Fig. 1 is shown the usual exhaust-hood,- H, placed over thecutter-head D, to remove the chips and prevent the dust from flyingabout the machine. Such a device removes the greater part of the looseparticles from the planed board; but to protect the printing deviceseffectually from injury by dust, I incloso them in a screen, G, which isadapted to in close all the working parts entirely, and to ef fect thisperfectly I form the boxes 6" so as not to project outside thestanchions b, and am thus enabled to cover the whole side of thestanchion by a plate, f, as shown in Figs. 3 and 6.

. In Fig. 4 is also shown aplate, (1, extended across between the boxes6, to support the ink-trough a, one edge of the plate being fitted closeto the impression-roller e and the other to the lower corner of thescreen G. Thei11king and other rollers are thus effectually inclosed,and the board is cleaned, before its admission to the roller. 0, by aflexible wiper h, which is secured to the front edge of the screen,-close to the board X, by means of an adjustable strip, h, and screws i,inserted in slots in the strip, as shown in the detached view in Fig. 5.The wiper is shown as a piece of yielding india-rubber cloth, but maybemade of any other flexible or yielding material, and may be readilyremoved by securing it to the strip h by a clamping bar or piece, at.

In Fig. l a blast-pipe, I, is shown connected with the top of the screenG, and an arm, I, indicates the influx of air from a blowerindependently operated. Such a blast would serve not only to clean offthe board as it entered the space within the screen G, but wouldeffectually prevent the penetration of an y dust inside the screen orits adhesion to the print ing or inking rollers.

The blower may, if desired, be attached to the planer, as at J, and beoperated by pulleys and a belt, 7;, fromthe counter-shalt B.

The distributirig-roller d is shown in Fig. 1 mounted in bearings 21,attached or formed upon the rollcrboxcs a, so as to rise and falltherewith as the printing or impression roller 0 is adjusted to thethickness of the board E, and the inking-roller c is shown provided withan adjustable doctor, 0, to regulate the amount of color transferred;but any other suitable means may be used for distributing the color tothe roller 0. The impressionroller may thus be used, if formed with asmooth surface, to uniformly coat the planed board with color, either inthe form of stain, paint, or ink; or the impressionroll maybe formed toprint any desired inscription or design. Thus in Fig. 2 the words PrizeSoap are shown impressed upon the board at regular intervals, and as theboard is readily cut apart on the sectiondincs n a after the planing andprinting operation, the labor of thus printing the boards is greatlyreduced. By such means the printing of boxes or box-stuff is greatlyfacilitated, as the labor of handling all the separate pieces andfeeding them to a printingmaeh'inc separately is avoided.

In Fig. 6 pulleys p are shown attached to the shafts of the dischargingfeed-roller C and the printing-roller c, and connected by a belt, q. Byproperly proportioning the pulleys p the roller 0 may be made to rotatewith the same surface-speed as the moving board. The roller 0 may alsobe operated by the board alone, and the impression be always applied tothe first end of the moving board correctly by means of abalance-weight, \V, attached by an arm to the axle of the roller 0, uponthe same side as the commencement of the desired impression. The rollerwould be unprovided with any pulley p or belt q in such a case and wouldbe constructed so as to turn freely in its bearings. It would thereforealways assume the position shown in Fig. 4-. in dotted lines at \V, whena board had been passed under it, and would always commence itsimpression in the same place upon all the boards fed into it, thesprings a securing a contact of the roller with the entering board andthe rotation of the roller by the boards movement.

Beyond the printing devices a second del ivery-roll, C is shown mountedin bearings in the usual manner, to remove the boards entirely from themachine after printing, and such roll 0 may be operated by anyarrangement of gear-wheels, as in common planingnachines, or by pulleysr r and belt 5, as shown in Fig. (5. When such roller is used, therotations of the printing-roller are readily secured without any drivingmechanism, as pulleys for the same, and the printedimpression is lessliable to damage when a board sticks fast in the machine, as issometimes the case, while the feedrollers are revolving.

In Fig. 7 is shown an alternative arrangement and construction for thebearings of the rollers c, (I, and c.

The bed of a planing-machine, as shown in Fig. 6 at A, is generallyprovided with slots 1, t. and to adapt my printing devices readily toexisting planingmachines I provide collared studs 1!, as shown in Fig.7, and secure them by nuts a through such slots t, near opposite edgesof the bed, beyond the deliveryroll C, and I construct the bearings forthe roller 0 to slide up and down upon such studs as desired. Nuts orcollars '1; maybe provided on the studs, to secure the bearings in thedesired positions due to the 'a-rying thicknesses of the boards 12, andthe inking devices would be attached to the bearings, as shown inFig. 1. The bearings of the auxiliary feed-roller C may be similarlymounted, and the required attachments thus be quickly made to anyplaninganachine having a bed of sufficient length.

In the cases herein mentioned, wherein the roller 0 is not provided withany direct connection, as pulleys p and belt 1 to the deliveryfeed-rollers C, it is obvious that the impressionroller c is operated asefficiently by the frictional contact of the board as if thus directlyconnected; and, indeed, such contact may be regarded as the-etlicient oroperative agent, even when the belt q is used, for it would in practicebe very difiicult to secure the precise speed for the impression-roller,as its surface would be impressed by the board if of soft composition,or would penetrate the board if of hard substance, and in either casewould somewhat affect the surface-speed of the roller 6. The belt (1would therefore require to bev loose enough or narrow enough to slip, ifneeded, to secure the required correspondence between the movements ofthe board and roller 0, and the board be permitted to controlthe speedor rotations of the roller.

I am aware that the different elements of my invention have been usedbefore, as in United States Patent No. 161, 726, issued April (3, 1875,and No. 182,416, issued September 19, 1876, and I do not therefore claimthe same as my invention; but having shown herein 110w I combine and usesuch elements to plane and print a board in a single continuousoperation, the nature of my improvement will be understood to consist intransferring the board automatically from the planing to the printingdevice, and in cleaning the surface of the board (11. 0., removing dustand chips) in the transit, so as to adapt the board to receive thesubsequent impression.

It is obvious that the ordinary operation of a planing-machine producesa great amount of dust and shavings, and that the joinder of a printingdevice thereto not only necessitates 5 the protection of the printingapparatus from such dust, but the effectual cleaning of the planedsurface before it is applied to the impression-roller 6. My process ofcontinuous planing and printing therefore involves the cleaning of theboard in its transit to the impression-roller, which cleaning is easilyeffected by the means described above, and thus the wiper h, and aprinting mechanism, as 20 the roller 0, the whole being combinedsubstantially as described, to plane, clean, and print the surface ofthe wood in a continuous operation, as and for the purpose set forth.

2. The combination, with the planing-machine having the cutter D andfeed-roller for propelling the boards, of the impression-rod er 0,provided with inking devices, and rotated by a'connection, as pulleys pand belt g, to the feedroller of the planing-machine, as and for thepurpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

\VILLIAM A. COMPTON.
